摘要
针对现行沥青路面检测评价体系不满足公路改扩建工程需求的问题,文章在对比分析现行检测评价规范规定的基础上,结合公路沥青路面设计规范对改扩建路面设计的需求,提出了包括路面损坏指数、路面车辙深度指数、裂缝率、车辙面积率、修补面积率、路面结构强度、结构层厚度、各结构层回弹模量、基层完整性的改扩建旧沥青路面检测指标与评价体系,并给出了指标的检测手段、计算方法与分级标准,最后引入特尔菲—理想点法进行使用性能的综合评价。
In regard with the problem that the current asphalt pavement detection and evaluation system does not meet the needs of highway reconstruction and widening projects,based on the comparative analysis of the current detection and evaluation criteria,and combining the requirements for pavement design set by the Specifications for Design of Highway Asphalt Pavement,a detection index and evaluation system for old asphalt pavement in highway reconstruction and expansion projects is put forward,which includes pavement damage,pavement rutting depth index,crack rate,rutting area rate,repairing area rate,pavement structural strength,thickness of structural layer,resilient modulus of each structural layer and the integrity.The detection method,calculation method and classification standard of the index are given.Finally,the Delphi-ideal point method is introduced to evaluate asphalt pavement performance comprehensively.
